HOME GASOLINE STATION.

Application filed July 17,1925. Serial No. 44,329. Q

My invention relates to improvements n home gasoline stations, and itconsists in the combinations, CODStlLlCtlOIlS, and arrangements hereindescribed and claimed.

providea home gasoline station of the type described which does awaywith all mechanical hand pumping, and which makes rse of the weight of.the caig'or the weight, of the operator "himself for forcing thegasoline from the reservoir up into the gasoline tank of the car.

A further object of my invention is to provide a home gasoline stationof the type described which is extremely simple in construction andwhich is durable and efficient for the purpose intended.

Ot ie-r objects and advantages will appear in the followingspecification, and the novel features of the invention will beparticularly pointed out in the appended claim.

My invention is illustrated in the accompanying orawing, forming part ofthis application, in whichi i Figure 1 is a side'elevation ofzthe deviceand Figure 2 is a. sectional view through a modified form of nozzle.

Figure 3 is a section along the line 33 of Figure 1. p

In carryin out my invention I provide a reservoir P, a pump cylinder Cand a platform P. A pipe 1 connects the reservoir R to the cylinder C. Astandpipe 2 communicates with the pipe 1 and has its free end connectedto a hose H by means of an elbow 3.

The gasoline is fed into the. reservoir B through an inlet pipe 4. Thisinlet pipe is normally covered by means of a cap 5. Then the piston 6 isa'tuated' in the cylinder C, it draws the gasoline from the reservoir Rpast acheck valve 7 and into the cylinder G. The movement of thegasoline from the reservoir R to the cylinder C is efiected when theplatform P is moved manually, bythe aid of the handle thereon fromthefullline position into the dotted line position. It will-be notedfrom the drawing that the piston rod 8 is housed in a tubular member 9so as to permit the ready movement of the rod when actuating the piston6.

After the gasoline has been drawn into the. cylinder C, the platform Pis moved downwardly by either the operator standing upon the platform orthe platform may be constructed so as to permit the car to run thereuponso as to have the weight of the' present form of the device, I haveshown the cylinder C as being large enough to is (613 8 a ppr Ximatelyone gallon of gasoline and have shown the reservoir R as being adaptedto receive fifty or one hundred gallons oi. gasoline. If the device isused by a single owner, the cyhnder C will be made a pic enough toreceive one gallon of gasoire. if, on the other hand, the device is isedas a gasoline station,v the cylinder C will be made larger so as toreceive a numofgallons of gasoline, and the platform the car to ride upupon the. platform, thus using the weight of the car to force the carmovethe platform downwardly. In the f will also be made larger so as topermit The downward movement of the platform P forces the gasoline fromthe cylinder 3 into the standpipe 2 and the hosel-l. The

mouth 10 of the hose H is placed in the inlet opening of. the gasolinetank previous to the moving of the platform P in a downward direction.vThe gasoline will therefore flow into the gasoline tank of the car. Thegasoline in flowing through the hose H passes a pet cook 11 and a secondcheck valve 12.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. I The check valve 12 isused for preventing air from flowing through the hose H and into thecylinder 0- when the platform P is Then therefore the platform P ischeck valve 12 permits the gasoline to flow out through the mouth 10,but prevents any back-flow of gasoline or air.

One of the principal features of the invention is to provide a device inwhich all of the gasoline will flow back into the cylinder C. After thedesired amount of gasoline has been pumped into the car, the operatoropens the pet cook 11 and allows air to enter the hose H. It will beseen that the gasoline in the hose H Will flow back into the standpipe 2and from thence to the cylinder C, as the piston is manually raised. Allof the gasoline Will nowv be disposed beneath the surface of the groundand will therefore be unaffected by changes in temperature. The novelconstruction of the platform P obviates the necessity of gears, etc. Thedevice is extremely simple in construction and is durable and eflicient'forthe purpose intended.

In Figure 2 I show a slightly modified form of nozzle in which the checkvalve 12 and the manually operated valve 11 are eombined so as toprovide a device of more simple construct-ion. This form of the deviceis preferably used When the platform P is made large enough to receive atruck or automobile and be actuated by the truck. The mouth is securedto the end of the hose H and the hose in turn houses a manuallycont-rolled spring pressed valve. This valve comprises a valve member 21that is normally held against a seat 22 by means of a coil spring 23.The spring bears against a perforated plate 24. A. crank 25 has itseccentric portion slidably disposed in a slot 26. The slot extendstransversely to the longitudinal axis of the valve member 21 so as topermit the handle 27 to swing the crank 25 and open the valve againstthe tension of the spring 23.

The check valve is normally closed and therefore prevents air fromentering through the mouth 20 and passing down through the hose H. Inoperation the platform P is raised in the ordinary manner to fill thecylinder G with gasoline. The valve member 21 prevents air from flowingthrough the hose H down into the cylinder C. lVhen the platform is inraised position, the car is driven upon the platform. The valve 21 remains closed and thus prevents the platform 1. from moving into the fullline position. Yi hen the operator places the mouth 20 in the gasolinetank of the car, he turns the handle 27 so as to open the valve andleaves the handle in open position until the desired amount of gasolinehas been forced into the gasoline tank. This gasoline is forced into thetank by the Weight of the car.

After the desired amount has been forced out, the operator closes thevalve 21 by the handle 27 and then after the car has been driven offfrom the platform, he opens the valve.

I claim:

A device of the type described comprising a reservoir for gasolinedisposed beneath the surface of the ground, a cylinder disposed beneaththe surface of the ground, a pipe connecting said reservoir With saidcylinder, a check valve disposed in saidpipe for only permitting thegasoline to flow from the reservoir to the cylinder, a piston mounted insaid cylinder, a platform adapted to receive a weight so as to actuatethe piston, a pipe for conveying the gasoline from the cylinder to thetank in an automobile, a check valve disposed in said pipe for onlypermitting the gasoline to flow through said pipe in one direction, anda pet cock for admitting air to said last named pipe so as to permit thegasoline in said last named pipe to flow into said cylinder beneath thesurface of the ground When said piston is raised a sufficient distance.
